Rewards Program Terms and Conditions
Last updated January 1st, 2020
Opting-in to Moosejaw Rewards:
All users must accept these terms and conditions and create an account with Moosejaw to opt-in to the program and earn, accrue, retain and redeem Moosejaw Reward Dollars (MJ$). The program is FREE to join and membership is ongoing until or unless the user requests to be removed or is removed due to abuse of the program. Users can opt-in to the program while checking out on Moosejaw.com or at one of our stores or at any time within 30 days of purchase to accrue the MJ$ earned on that purchase. Once opted-in to the program, MJ$ will earn and accrue for redemption as described below until the MJ$ expire or the user leaves the program.
All information collected and used to facilitate the Moosejaw Rewards program is directly related to the program's ability to provide value to the customer. A customer opting-in to the Moosejaw Rewards program is a separate action from establishing a user profile as a result of making a purchase.
The program opt-in requirement was added on August 6th, 2019. Existing program members prior to that date must still formally opt-in and accept the terms and conditions to continue to retain, earn and redeem MJ$. Pre-existing program members that fail to opt-in prior to June 28, 2020 will be removed from the program, and any unused MJ$ will be voided. We really, really don't want to that to happen, so please opt-in or we'll feel terrible.
Leaving Moosejaw Rewards Program:
You may choose to leave the Moosejaw Rewards program at any time by logging in and clicking on the “Opt out Rewards Program” link within the My Account Summary page, Email, calling 877-MOOSEJAW (877-666-7352) or in-store with help from our employees. If you leave the rewards program, any unused MJ$ will be voided upon completion of your request.
Earning MJ$:
All items we sell are eligible with the exception of gift cards or other items specifically noted. Full-priced items earn 10% back while discounted items earn 2.5%. "Discounted items" includes items on sale or discounted via coupon code or use of MJ$. You do not earn MJ$ for shipping or tax charges, only from the item value. MJ$ expire two years after earning and are redeemed on a first-in, first out basis (in other words, we always use your oldest MJ$ that are closest to expiration).
Checking & Redeeming MJ$:
On Moosejaw.com, just sign-in on any page to see your available balance. Once signed in, you will see your available MJ$ and maximum that can be redeemed in the payment section of the checkout process. In stores, provide the email address attached to your account to learn your balance and apply to your purchase. We will also send you a monthly email that details your balance and other account activity. This is a transactional email that you will receive even if you are not subscribed to our marketing emails.
Bonus Rewards Promotions:
Every so often, we'll have special offers where you can earn bonus MJ$, like an additional 10%, 20% or 40% back. So if we are running a 50% back special offer, and you buy a regular-priced item for $100.00, you will receive MJ$10.00 in base points, and a bonus of MJ$40. These special offers may have a cap on how many bonus MJ$ you earn during the promotion, but you will always earn the base Reward Dollars. Make sure to check us out on our social channels for other ways to win some extra MJ$!
MJ$ on Gift Cards:
You don't get earn MJ$ when you buy a gift card, but you do get MJ$ when you spend a gift card. Sorry gift givers. You're welcome gift receivers.
Product Returns and MJ$:
If you return an item, we deduct the MJ$ earned on that item from your balance. If you used the MJ$ and your balance is less than deduction, then your refund is reduced by the difference.
Program Abuse:
The intent of the program is to provide our loyal customers with a way to buy great gear for less. Moosejaw reserves the right to remove any user from the program and zero out their MJ$ balance if Moosejaw determines that the user is abusing the program by buying for resale, attempting to game the program or any other reason at Moosejaw's sole discretion.
Are you Sure?
Our Rewards Program is completely FREE and easy to use.
By opting out, you forfeit all the Moosejaw Rewards Dollars your currently have in your account, which is basically throwing away free money. What would your grandmother say about that? If you're 100% sure, please click "OptOut" below.
Earn 10% back on all full-priced purchases on Moosejaw.com or at our shops (2.5% for discounted items).
The program is FREE. Just register and join during the checkout process. So Easy.
After joining the program, you'll receive your MJ$ as soon as your order ships. Then the next time you shop at Moosejaw, you can redeem those MJ$ to get awesome gear for way less.

Special order items take longer to ship
We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first.

A sleeping bag that keeps you warm in a cold nightThis sleeping bag can keep you warm even in a very cold night. The quality is quite decent, puffy and thick that keep the warm air inside the bag, I tried it during the cold and windy period when I went to a camping trip, it helped to give a good and warm night of sleep, but only one complaint is that it is not easy to pack it back, however, still recommend this sleeping bag.

So comfy!Perfect for 2, or 1 person who tend to toss and turn a lot while sleeping (me). I haven't used it in temps below 35F, but I suspect it will be a bit chilly. The first time I used it, I did not want to get out because it is so very comfortable.
I use this for car camping. When packed in its bag, it is quite large, which is not an issue for car camping. There is no way you could carry while backpacking, though.
There is a trick to packing it back in the bag. Do not roll it first. Stuff it in, feet first so that the air can escape through the top. Even doing it this takes a bit of effort.

Comfort for Big Bend Tent Camping ExpeditionMy wife and I purchased this sleeping bag about 3 weeks ago for our trip to Big Bend National Park, and we couldn't be happier with its performance!
This bag has plenty of room for two people and the height of the bag was perfect. I'm 6'1'' and my wife is 5'5''. The bag didn't swallow her up and I also didn't feel even the slightest bit claustrophobic. They really nailed both the length and width on this bag.
The temperatures were uncharacteristically cold during our visit to Big Bend, with temperatures dropping into the mid to lower 30s (Fahrenheit) each night. We stayed plenty cozy with this bag. My wife is cold-blooded. She literally is just physically cold all of the time, and this bag kept her nice and toasty. I, however, did have to strip down to just my underwear in order to keep from getting too hot, but that really boils down to each individual. Also, keep in mind that we were using our Exped duo sleeping mat underneath this bag, and it has a pretty high R-value. I'm certain that it contributed to our comfort level as far as temperature is concerned as well.
The overall quality of this bag is also excellent. The zippers on both sides function just as they should from both inside and outside of the bag. The material on the inside is soft and warms up quickly once you're tucked inside. Overall, we are extremely pleased with this Teton sleeping bag, and we look to enjoy tent-camping with it for many years to come.
One additional note: I saw a couple of slightly negative reviews about getting this sleeping bag to fit back into its storage bag. We had no such issue. I'm assuming those folks might have been attempting to roll it up and trying to stuff it into the sack. This won't work, but if you simply start from the bottom and keep stuffing it down with the compression straps loosened, you'll be just fine.
Happy adventuring!

It's a keeper!The bag is roomy and comfortable. Not made for the "in-between" temps though. No doubts that it will perform well in colder temps. And getting it back in the bag.....yowza!

Space, the final frontierAs a larger person I've struggled to find a comfy sleeping bag that didn't make me wake up in a panic in the middle of the night dreaming I was trapped in a giant spider sack and on the menu for later. Girth is good in a bag. Car camping makes it easier to justify space and weight. This bag would never go backpacking unless it was the only thing to go in a pack. I love the soft fleecy interior and can't wait to sleep in it in the new stealth truck camping shell.

Great bag with small flawThis is an excellent bag. It's large, well insulated, and extremely comfortable. The only real flaw is just how difficult it is to put back in it's bag. I genuinely felt like I'd just wrestled a crocodile after putting it away. The bag needed to be ever so slightly larger.

Can you unzip the 2 halves completing apart? It would make washing much easier if so.
Asked by: Charlie
Good news everyone!
Yes it can, the double TETON Sports Mammoth +20F Sleeping Bag can be completely unzipped to form two toothy camp blankets. And as you said, this is also helpful if you want to break it up for packing smaller or washing!
I hope this helps!
